Learn more, 1. How to dynamically allocate a 2D array in C? Of course it's impossible to compare multiple items without looping. The strcmp() function consider two strings as a parameter, and this function returns an integer value where the integer value can be zero, positive or negative. This would be better: Itd also be better if you use strncmp which is safer in general (if a character array happens to be NOT NULL-terminated). Each String is terminated with a null character (\0). The highly interactive and curated modules are designed to help you become a master of this language.'. 1. Vector of Vectors in C++ STL with Examples, Tree Traversals (Inorder, Preorder and Postorder). If the first character of both the strings are same, then this process of comparison will continue until all the characters are compared or the pointer points to the null character '\0'. It is an application of a 2d array. Each String is terminated with a null character (\0). In C programming String is a 1-D array of characters and is defined as an array of characters. This function starts comparing the first character of each string. The following example uses the CompareOrdinal method to compare the values of two strings. C++ However, you may visit "Cookie Settings" to provide a controlled consent.
